include/smb.h: Removed dir_ptr. Not needed.

locking/locking.c: First cut a blocking lock code. #ifdef'ed out for now.
locking/locking_shm.c: Removed dir_ptr. Not needed.
smbd/nttrans.c: More work on ChangeNotify - return is not an error and needs
                to be handled as a nttrans with zero params. Removed dir_ptr. Not needed.
smbd/reply.c:
smbd/server.c:
smbd/trans2.c: Removed dir_ptr. Not needed.

Hmmm. At the moment smbclient is broken - doesn't issue prompt correctly.
This needs looking at.

Jeremy.
